What equipment is needed for this? Are there write ups where I may research?

I think it better to contact Landon on this.

To do the job properly a lathe is required, along with the skill to use it. A drill press might do the trick if you’re careful. Probably better to contact someone who knows what he’s doing as noted above.

If you are just chasing the threads you can probably get by doing it by hand. Chasing refers to running a tap into slightly damaged threads to straighten them out. It won’t fix a stripped thread.
